did you try 192.168.1.249?
I think the software takes the network address and replaces the last number by 249, so if your network is 192.168.11.x your bitfury will be 192.168.11.249.
You can probably get a list of clients by browsing to your access point ip address.
It uses dhcp and gets the first free ip from your router/switch... just look it up in your router or switch.
